ZF 4644.152.217 CLUTCH for WG 180/WG 200 | OEM Genuine Part

Overview

The ZF 4644.152.217 CLUTCH is a critical friction component engineered for the WG 180 and WG 200 series transmissions. This OEM genuine part manages torque transfer between planetary gear sets, enabling smooth gear engagement under heavy load conditions. Positioned within the clutch drum assembly, the SKU 4644.152.217 directly controls hydraulic pressure application to lock or release specific gear ratios. When paired with a properly functioning 4644105475: DISCONNECTION unit, this clutch ensures precise shift timing and prevents driveline shock during power take-off operations.

Symptoms of Failure

• Delayed gear engagement: Operators may notice a 2-3 second lag when shifting from neutral to drive, indicating worn friction material on the 4644.152.217 clutch pack.
• Transmission overheating: Slipping clutches generate excessive heat, often triggering thermal warning lights on WG 200 series equipment.
• Erratic shifting under load: The transmission may hunt between gears or produce grinding noises when the clutch fails to hold torque, particularly during uphill climbs.
• Low hydraulic pressure readings: A worn clutch can cause internal leakage, reducing system pressure below the 12-bar threshold required for proper operation.

Technical Specifications

Compatibility

This clutch is designed exclusively for ZF WG 180 and WG 200 series transmissions, including all sub-variants such as WG 180-1, WG 180-2, WG 200-1, and WG 200-2. It replaces earlier clutch packs with identical dimensions. For complete assembly, verify the condition of the 4642303097: OUTPUT FLANGE and 4644101134: TRANSMISSION HOUSING during installation. Secure the clutch pack using 0636020211: HEXAGON SCREW fasteners torqued to 45 Nm.
